Error executing test: #5

Closed jschappet closed 10 years ago

jschappet commented 10 years ago

I am trying to run the following test: @Rule public CassandraCQLUnit cassandraCQLUnit = new CassandraCQLUnit(new ClassPathCQLDataSet("tcgadata.cql","tcgadata"));

@Test
public void should_have_started_and_execute_cql_script() throws Exception {
    ResultSet result = cassandraCQLUnit.session.execute("select * from mytable WHERE id='myKey01'");
    assertThat(result.iterator().next().getString("value"), is("myValue01"));

  }

Using: cassandra-unit-spring 2.0.2.1-SNAPSHOT

And I get the following exception, looking at this yaml file, I do see the cas timeout setting.

09:55:16,556  INFO DatabaseDescriptor:132 - Loading settings from file: target/embeddedCassandra/cu-cassandra.yaml

Hi,

It looks like a classpath problem

Could you check the version of cassandra you're using in your classpath?

jschappet commented 10 years ago

Yep, still had cassandra-all 1.2.8 in my POM File. Thanks

yukevinchen commented 10 years ago

I have this exactly same error. Can you shed some light on how to fix it? These are the dependencies in my pom file:

    <dependency>

Thanks!

I met same problem. Can anyone enlighten me on this? Thanks!

swathiselv commented 9 years ago

Yes, please what is the solution here?

looser990 commented 9 years ago

I'm getting the same error here. We are trying to switch to cassandra driver 2.1.6. and newest version of cassandra-unit. Am I right if I think the problem is in cassandra-all version missmatch between driver and cassandra-unit or is there other problem involved here?

jsevellec commented 9 years ago

Hi,

I think this pull request is about to solve your classpath problem : https://github.com/jsevellec/cassandra-unit/pull/120

looser990 commented 9 years ago

Tested with versions: 2.1.3.2-SNAPSHOT and '2.1.3.1'. Others had some more luck? pom:

jsevellec commented 9 years ago

the pull request i mentioned is about a new artifact : "cassandra-unit-shaded". It would be great if you could give a try using it instead of the cassandra-unit dependency to see if it solves your issue

looser990 commented 9 years ago

Working with shaded artifact like a charm! Thanks! When we can expect release version of it?

jsevellec commented 9 years ago

I'm waiting a bit for feedback and will perhaps just apply the shaded stuff into the same artifact id instead of having a dedicated one. It might be for this month.

looser990 commented 9 years ago

Neat. I support this to go in the same artifact id. Keep up the good work.
